  • Preventives and/or remedies for hyperphosphatemia
    Patent number: 7087223
    Abstract: Provided in a phosphate ion adsorbent containing a weakly basic anion exchange resin as an active ingredient which aims at providing preventives and/or remedies for hyperphosphatemia having a high selectivity for the adsorption of phosphate ion and showing an effect of lowering blood phosphorus level and another effect of suppressing phosphorus excretion into the urine.
    Type: Grant
    Filed: November 9, 2004
    Date of Patent: August 8, 2006
    Assignee: Hisamitsu Pharmaceutical Co., Inc.
    Inventors: Takeshi Goto, Kazuhisa Yoshitake, Hiroshi Sorimachi, Kazuteru Moriyama

  • Crosslinked anion-exchange resin or salt thereof and phosphorus adsorbent comprising the same
    Patent number: 6844372
    Abstract: An cross-linked anion exchange resin or a salt thereof obtained by reacting a polymer (A) having amino and/or imino groups in the total number of two or more per molecule with a compound (B) having two or more functional groups capable of reacting with amino and/or imino group contained in the polymer (A). The resin or salt has a water absorption ratio of 4.0 or lower.

  • Crosslinked anion-exchange resin or salt thereof
    Publication number: 20040059065
    Abstract: A crosslinked anion exchange resin or a salt thereof obtained by reacting a polymer (A) having amino and/or imino groups in the total number of two or more per molecule with a compound (B) having a vinyl group capable of reacting in Michael addition reaction and a carboxylic ester group, and thus by making the amino and/or imino groups contained in the polymer (A) add to the vinyl group in the compound (B) and form a amide-bond with the carboxylic ester group in the compound (B).
